Insights

Hepatitis C virus (HCV) is the primary cause of posttransfusion hepatitis (PTH). While some patients also show Hepatitis B virus (HBV) markers, further research is needed on HCV and HBV interactions.

Area of Science:

  • Hepatology
  • Virology
  • Infectious Diseases

Background:

  • Posttransfusion hepatitis (PTH) remains a concern following blood transfusions.
  • Identifying causative agents is crucial for effective prevention and treatment.

Purpose of the Study:

  • To investigate the etiological agents of posttransfusion hepatitis (PTH) in 169 patients.
  • To determine the detection timeframes for Hepatitis C virus (HCV) antibodies and RNA.
  • To analyze the patterns of HCV viremia in a follow-up cohort.

Main Methods:

  • Serological testing and Polymerase Chain Reaction (PCR) were employed.
  • Detection of anti-HCV antibodies and HCV RNA.
  • Follow-up serological and viremia assessments over 1.5 to 3 years.

Main Results:

  • Hepatitis C virus (HCV) was identified as the predominant cause of PTH.
  • Hepatitis B virus (HBV) markers were positive in 24 out of 169 patients.
  • Anti-HCV antibodies appeared within 7 days to 1 year (average 54.62 days); HCV RNA was detected earlier (average 8.72 days).
  • Follow-up revealed transient, persistent, or intermittent HCV viremia in all patients, with sustained anti-HCV positivity.

Conclusions:

  • HCV is the main etiological agent in posttransfusion hepatitis.
  • Early detection of HCV infection is possible through RNA testing.
  • HCV viremia patterns vary, and the interplay with HBV requires further investigation.

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
